So IOTL McVeigh was caught for two reasons. First, he was driving without license plates, which led to a cop pulling him over and then noticing he had an unlicensed concealed weapon. Despite a popularly repeated misconception, the plates weren't knocked off in the blast. When McVeigh stashed his getaway car he left a note on the dash covering the Vehicle Identification Number that said, "Not abandoned. Please do not tow. Will move by April 23. (Needs battery & cable)." Then he removed the plates so that no one would be able to note the numbers in the meanwhile. It looks like in the adrenaline of everything he forgot to reattach them. The second thing he did wrong was use his real name at the hotel (he had been using fake ones before). The lady at the hotel who signed him in, Lea McGown, said later, per wiki, "People are so used to signing their own name that when they go to sign a phony name, they almost always go to write, and then look up for a moment as if to remember the new name they want to use. That's what [McVeigh] did, and when he looked up I started talking to him, and it threw him." The FBI was able to find the rear axle of the Ryder truck two blocks from ground zero and traced the serial number to a certain rental dealership, then followed the trail to the hotel where McVeigh was registered under his real name, they ran his SSN and found out he was sitting in the OKC courthouse in a holding cell waiting to be arraigned for the weapons charge and for driving without plates. The rest, as they say, is history.
So the POD is that Lea McGown doesn't say anything and McVeigh puts down his alias, which leads to some subtle mental butterfly in his train of thought that makes him remember to screw the plates back on before he gets driving. He gets away clean. What happens? There wasn't really anything else that could tie him to the bombing, so if he just never did anything criminal again it would probably go unsolved forever, like the Zodiac Killer case or the Golden State Killer one looked like it would be until a month ago. IMHO, the cloud of suspicion over Middle Eastern people that briefly took over would dissipate because it was pretty obvious from the beginning who in general had done it. The bombing was on the anniversary of Waco and neo-nazi/militia types were strong in the area and had targeted the building before. It was either them or drug traffickers, because the Alfred P. Murrah building was nexus for most federal law agencies in the area, but they generally don't do that kind of thing. Where it goes from there is anyone's guess.
McVeigh probably doesn't stop there, though. He and Nichols were very committed and they still had a ton of bomb-making materials and they probably would have had their egos fed by the success of this.
So what happens?
